am.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, (triggerAtTime + time), pi);2、闹铃时间优化
public class AlarmTime { public static final AtomicLong alarmTime=new AtomicLong(0); /** * 初始化闹铃时间,重连或者收到消息初始化一下 */ public static long initAlarmTime(){ alarmTime.set(Global.ALARM_TRIGGER_TIME); return alarmTime.get(); } /** * 优化闹铃时间,重连错误数超过一定次数,优化闹铃时间再尝试重连到错误数 * 10分钟,30秒、30秒、;;;;到达错误数,10分钟 ;;;;; * @return */ public static long optimizeAlarmTime(){ alarmTime.set(Global.ALARM_TRIGGER_OPTIMIZE_TIME);//10分钟 return alarmTime.get(); } public static long incrementTime(){ long time =alarmTime.get(); if(time==0) return alarmTime.addAndGet(Global.ALARM_TRIGGER_TIME);//默认30秒开始 else if(time<Global.ALARM_TRIGGER_MAX_TIME)//25分钟 return alarmTime.addAndGet(Global.ALARM_TRIGGER_TIME_INCREMENT);//每次递增5秒 else return time; } }3、唤醒机制
public final class IMWakeLock { private static final String TAG = IMWakeLock.class.getSimpleName(); private WakeLock wakeLock = null; private String tag=""; private PowerManager pm; public IMWakeLock(Context paramContext,String tag){ this.tag =tag; pm= ((PowerManager) paramContext. getSystemService(Context.POWER_SERVICE)); wakeLock = pm.newWakeLock( PowerManager.PARTIAL_WAKE_LOCK , tag); } /** * 获取电源锁,保持该服务在屏幕熄灭时仍然获取CPU时,保持运行 */ public synchronized void acquireWakeLock() { if(!pm.isScreenOn()) { if (null != wakeLock&&!wakeLock.isHeld()) { ImLog.d(TAG, tag+"@@===>获取唤醒休眠锁"); wakeLock.acquire(); } } } /** * 释放设备电源锁 */ public synchronized void releaseWakeLock() { if (null != wakeLock && wakeLock.isHeld()) { ImLog.d(TAG, tag+"@@===>释放唤醒休眠锁"); wakeLock.release(); } } public synchronized void finalize(){ if (null != wakeLock && wakeLock.isHeld()) { ImLog.d(TAG, tag+"@@===>释放唤醒休眠锁"); wakeLock.release(); } wakeLock = null; } public boolean isScreenOn(){ return pm.isScreenOn(); } }4、唤醒时机
